IFC
International Fire Code

What Is the IFC?

The International Fire Code (IFC) is a model fire prevention code developed and maintained by the International Code Council (ICC). Published alongside the International Building Code (IBC), the IFC serves as its companion code for existing buildings and ongoing operations. While the IBC governs how a building is designed and constructed, the IFC governs how that building is operated, maintained, and kept safe after the Certificate of Occupancy is issued. IFC 2024

The IFC is updated on a three-year cycle, with the 2024 edition being the current release. Like the IBC, adoption varies by jurisdiction — some states adopt the IFC statewide, while others allow local adoption. The code is enforced by the fire marshal or fire code official rather than the building official, reflecting its operational (rather than construction) focus.

Fire Code vs. Building Code

Understanding the distinction between the IFC and IBC is fundamental for fire and life safety professionals:

Key Chapters for Fire and Life Safety

Key Operational Requirements

The IFC imposes a wide range of ongoing operational requirements that building owners, facility managers, and fire safety professionals must maintain:

Fire Watch

When a required fire protection system is out of service, the IFC mandates a fire watch — trained personnel performing continuous patrols of the affected area with the means to notify the fire department and building occupants. Fire watches are also required during hot work operations (cutting, welding, grinding) per IFC Chapter 35. IFC 901.7

Hot Work Permits

Any cutting, welding, or open-flame operation requires a hot work permit under IFC Chapter 35. The permit system requires designated responsible individuals, fire watch during and after operations (typically 30 minutes minimum), verification of sprinkler system status, and removal or protection of combustibles within 35 feet.

Means of Egress Maintenance

The IFC requires all means of egress to be continuously maintained free of obstructions. Exit doors must be operable without special knowledge, exit signs must be illuminated, and emergency lighting must be tested monthly (30-second test) and annually (90-minute test). Locked exit doors are among the most frequently cited IFC violations. IFC 1031

Hazardous Materials Storage

IFC Chapters 50 through 67 regulate the storage, handling, and use of hazardous materials in occupied buildings. This includes maximum allowable quantities (MAQs) per control area, required ventilation, spill containment, and specialized suppression systems. Exceeding MAQ thresholds reclassifies the space as a Group H (High Hazard) occupancy under the IBC, triggering significantly more restrictive construction and protection requirements.

How the IFC References NFPA Standards for ITM

One of the IFC's most important functions is establishing the legal framework for inspection, testing, and maintenance (ITM) of fire protection systems. IFC Chapter 9 states that fire protection systems shall be maintained in accordance with the applicable NFPA standard. This makes the following ITM schedules legally enforceable in any jurisdiction that adopts the IFC:

• NFPA 25 — Inspection, testing, and maintenance of water-based fire protection systems (sprinklers, standpipes, fire pumps, water storage tanks).
• NFPA 72 — Inspection, testing, and maintenance of fire alarm and detection systems.
• NFPA 10 — Inspection, maintenance, and recharging of portable fire extinguishers.
• NFPA 80 — Inspection, testing, and maintenance of fire doors and other opening protectives.
• NFPA 96 — Maintenance and cleaning of commercial cooking ventilation systems.

This referencing mechanism is what gives NFPA ITM frequencies their regulatory teeth. Without the IFC (or an equivalent state fire code), NFPA standards would be voluntary consensus standards rather than enforceable requirements. IFC 901.6

Fire Department Access and Key Boxes

IFC Chapter 5 establishes requirements for fire apparatus access roads — minimum 20-foot width, 13-foot 6-inch vertical clearance, and all-weather driving surface capable of supporting 75,000 lbs. Dead-end access roads exceeding 150 feet require an approved turnaround. These requirements apply to all new buildings and may be retroactively applied to existing buildings when deemed necessary by the fire code official. IFC 503

Key boxes (commonly Knox Boxes) are required by IFC 506 when the fire code official determines that access to a building or area is necessary for life-saving or firefighting purposes. The key box must be an approved type, listed, and installed at an approved location — typically near the main entrance at a height accessible to firefighters. The box contains building keys, access cards, and information needed for emergency response.

Fire department connections (FDCs) must be visible, accessible, and properly identified per IFC 912. Obstructed or damaged FDCs are a common citation during fire inspections because they directly impact the fire department's ability to supplement the building's water supply during a fire event.

Georgia Adoption Status

Georgia adopts the IFC through the Georgia Department of Community Affairs (DCA) and the Safety Fire Commissioner under O.C.G.A. §25-2-12. The state has adopted the 2024 IFC with Georgia amendments, effective January 1, 2026. State amendments address Georgia-specific conditions including local climatic data, LP-gas regulations, and fireworks provisions. O.C.G.A. §25-2-12

Enforcement authority in Georgia is shared between the State Fire Marshal's office (which has jurisdiction over state-owned buildings and buildings in unincorporated areas without local fire marshals) and local fire marshals in cities and counties that have adopted local enforcement. As with the IBC, always confirm the locally enforced edition with your AHJ.
